Specification of Letters Patent.

Patented Sept. 1, 1908.

To all whom it may concern:

Be it known that we, EDWARD F. LEEDS and GEORGE RUMPF, citizens of the United States, residing, respectively, in the county of Kings and in the county of New York, city and State of New York, have invented new and useful Improvements in Phonographs, of

which the following is a specification.

described with reference to the drawings which form part of this specification.

Referring to the drawings, Figurev 1 is a lan view, and Fig. 2 is an elevation, partly mvertical' section, of aphonograph made in accordance with this invention l Fig. 3 is a plan view, partly in horizontal section along the line ab, of a detail. of thei -phonograplh Fi .4isaplanwiewoft e mechanism within t e boxof the phonograph shown in Figs. 1 and 2. Fig: 5 is an elevation, partly in vertical sectionalong the line rd, "of mechanism shown in Fig. 4. Fig. 6 is an elevation, partly in vertical section along the line 62, of mechanism shown in Fi 4. Fig. 7 is an elevation, partly in de- -ve oping section along the line gzfofa detail of the mechanism shown in Fig. 4. 1 Fig. 8 is an elevation'of the mechanism shown in Fig. 4, viewed from the right side thereofyp Fig. 9 is an elevation, partly in vertical section along the line jz, of a detail of the mechanism shown in Fig. 8. Fig. 10 isa plan viewof that part of the mechanism shown in Fig.

8 which is below the line l2.

Referring to Figs. 1 and 2, A is abox, of

- any suitable sha e and materiah-in' which the greater part of t e mechanism of the phonogra h is preferably placed; B is a-reconitab et, shown in the form'off a disk having a sound-record made thereon. The recordtablet B may, howevenconsist of sound-recording material and be of'any suitable shape or size. C is a. suitable support for the record-tablet B and may, as shown, consist of a disk of metal provided, preferably, with a covering D of felt or other suitable material upon its surface next to the tablet B. E is an arm secured to and extending from, one side of the box A. The arm E may be provided at its end with a cavity F, having recesses or sockets {f and f as shown in Figs. 2 and 3. G is a bi urcated piece provided with two pins pand p, enteringand fitting respectively into the sockets f and f, and with a pivot 9 upon which the bracket H, which supports the horn I, turns verticall J is a sound-recorder. or a sound-repro ucer adjusted at the small end of the horn I and provided with a diaphra m and with a stylus s that vibrates vertical y, or, as shown, that vibrates laterally in the recording and reproducingof sound. K is a revoluble shaft ex tending u "through the top of the box A and carrying t e metal plate 0, together with the tablet Bfi L is an opening, oblong and.

slightly curved, as shown by dotted lines in Fig. 1, in the top of the box to permit the to and fro, lateral or transverse motion of the revoluble shaft K, which, when it revolves, moves transversely and causes plate C and tablet B in like manner to revolve and'to *move transversely and thus' to pass across the point of the sound-recording or of the sound-re roducing stylus. As hereinafter shown, t e revoluble shaft-K,moves transversely in the arc of a. circle.

The stylus s of he sound-box J is free to move up and down or vertically by virtue of the pivot g upon which the bracket H, which carries the horn I, turns. As'shown in Figs. 1 and 2 the connection between the small end of horn I and sound-box J may consist of a rubber tube Q, the fiexibilit of which will permit stylus s to adjust itse f automatically to the thread or groove of a sound-record and to gravitate to the bottom of the groove; or as'shown in Figs. 2 and 3, the pin pneed not quite fill the recess so that the part G is capable of a slight lateral motion by the turn of the pin p in its socketf, whereb the st inc 8 of the sound-box J is capable of such slight lateral motion as, will enable it, in like manner, to adjust itself automatically to the thread or groove of a sound record and gravitate to the bottom of the groove. Since the threads or grooves of a soundrecord approximate 100 to the inch, the lateral motion of.

' shaft K, is permitted to pass across the point of stylus s, and in such manner that stylus 8 would, if tablet B did not revolve but moved only transversely, describe the arc of a circle in suitable recordin material upon the sur face of tablet B, is illustrated in the remaining Figs. 4-10 of the drawings and described as follows,'1 is a bed-plate provided with screw-holes 2 at the corners for the assage of screws to secure the bed-plate to t e bottom of box A.

3 is a plate'parallel to and elevated above bed-plate ,1 and supported by chine.

three standards 4. In Fig. 8 plate 3 is shown as consisting of a single piece of metal, while in Figs. 4,-5 and 6 it is shown as consisting of two pieces, 3 and 3. 5 is a casing containing a motor or main spring which is attached at one end to and winds about a vertical shaft 6. The casing 5 is provided with a gear wheel'7 and a worm 8 which revolve with the casing under the action of the spring, as is well understood, and, respectively, communicate motion to the two principal, operative systems or parts of the maabove plate 3, is a wheel 9. The wheel 9 is provided on its lower side with a cylindrical piece or sleeve 10 which surrounds shaft 6, passing through plate 3, and engages a pin 11, which passes through shaft 6. riphery of wheel 9 is provided'with perforations 12, shown in Fig. 4, or with a crown gearor ring of vertical cogs instead of the perforations 12. The cogs or perforations" 12 on the periphery of wheel 9 are engaged'by gear-wheel 13 which revolves at the end of shaft 14. The shaft 14 revolves in bearings in the standards 15 and is provided with one or more projections 16 to engage a key adapted to enter the hole in the side of the boX shown in Fig. 2 and turn or revolve shaft 14. When shaft 14 revolves, gear-wheel 13' revolves with it and causes thelperforated or gear-wheel 9 to revolve, whic being connected with the main spring in the manner described, winds up the main spring.

In order to prevent the backward unwinding of the maln s ring, a stop 17, made of a flat piece of meta or in other suitable manner, 1s interposed between gear-wheel 13 and the perfora ions or cogs of wheel 9. The stczp 17, as shown in the drawings, forms the en of one arm of a bi urcated, fiat piece of Attached to the upper end of shaft 6,

The pemetal 1.8 which turns upon a pivot consistpiece 18, by coming in contact with gear wheel 13, prevents the piece 18 from revolving or moving beyond a'distance sufficient to carry stop 17 away from between wheel 13 and the perforations or cogs cf wheel 9. Upon ceasingto wind up the main spring,

the action of the main spring causes wheel 9 to begin to revolve in the op osite direction, carrying with it, by virtue o the friction described, the bifurcated piece 18, so that stop 17 returns to its position between gear-Wheel 13 and the perforations or cogs of wheel 9, where it remains and prevents the backward unwinding of the main spring. v 22 is a vertical shaft upon which two carwheels 23 and 24 revolve together. wheel 23 meshes with gear-wheel 7 and gearwheel 24 meshes with gear-wheel 25, which revolves together with gear-wheel 26, causj ing vertical shaft 27. to revolve atthe same Gear-wheel 26 meshes with gear time. wheel 28 which causes governor 29, provided with disk 30, and vertical shaft 31 to revolve with it.

v 32 is a piece of leather or other suitable material carried by an arm 33 ofa lever, the arm 33 being raised by the pressure of spring 34 or lowered by the movement of arm 35 or 'arm 36 of the lever-piece. Screw 42 in I standard 41 forms the fulcrum for levers 3533 "and 36-33. Y

37 is a screw which turns in its bearing in standard 41 and may thus be brought to bear against arm 35 and lower the free end of arm 33.. 4

38 is a flat piece of metal pivoted about the lower end of standard 41 and provided with a raised tongue 39 which, when brought in contact with arm 36, will also lower the free end of arm 33. The piece 38 moves over a slightly inclined piece of metal 40 which assists tongue 39 in elevatin 'arm 36. As is well understood, w en the end of arm 33.is lowered and the piece of leather or other material 32 is brought to bear upon disk 30 of the governor 29, the speed of the revolving parts may be regulated as desired, or the motion of the parts may be sto ped altogether.

Th e. screw 37 is used to regu ate the machine so as to secure the desired, proper speed, while piece 38 is used in the ordinary starting I25 and stopping of the machine in use for the recording or reproducing of sound. Shaft 27. revolving asstated with gearclent friction to cause it to 70 whegls 2,5 and 26, extends above plate 3 and carries at its upper end gear-wheel 43 which municated from shaft 27 throu h gear-wheels 43, 44 and 45, and with shaft late C and 7 tablet B revolve as above descri ed.

N is a carriage which may, as shown, he formed-of a bent, sultable strip of metal. The carriage is pivoted at one end by means of a collar or sleeve 46 surrounding shaft 27 and fitting,, revolubly, in the perfopro 'ecting partiall ration in plate 3 through which the ,upper part of shaft 27 passes. The collar 46 is provided with projecting rings 47 and 48 above and below plate 3, respectively, in orderto maintain it and parts connected with it in proper position; The lower ring 48 is detachable and-held fast by a s'etscrew 49.

The carriage N carries the pivot for e'arwheel 44 and bearings for revoluble sha t K.

As clearly shown in'Fig. 8, carriage N is so bent or formed that it is elevated above plate 3 except at the end where it is pivoted.

At theopposite end of the lower part of carriage'N and secured beneath it, a slidingrest 0 is provided,adapted to rest upon and slide over the surface of plate 3 and to support the weight-of, carriage N and parts carried byit, including revoluble shaft K, plate C and tablet B. Sliding-rest O maly, if desired, be'provided with'one or more ro lers, resting upon the surface of plate 3, to lessen friction.

Between plate 3 and carriage N is a fiat fan-shaped piece of metal 50 which is pivoted at one end and held in position in the manner above described for carriage N. The pivoted ends of carriage N and of piece 50 are suitably secured together, as by friction, as

shown or by making carriage N and piece 50 of one piece of metal so that carriage Nand piece 50 revolve or move together. Piece 50 should, fpreferably, be ap roximately in the shape 0 a sector of .a circ e and be revoluble about the center of the circle and should,'

near its circumference, be provided with perforations 51, or otherwise adapted as by cogs, forming a rack, to engage with gearwheel 52 carried by one end of shaft 53 and above plate 3 through pe oration 54. he top of gear-wheel 52 acts as a laterall -moving feed-piece to communicate latera motion to carria e N and -partsl1connected and movable t erewit-h.

Shaft 53 carries at its other end ear-wheel 55 which meshes with worm 8. 11's as the main spring, motor or other suitable source of power causes worm 8 to revolve, motion is communicated, through ear-wheels 55 and 52 carried by shaft 53 to t e revoluble, metalpiece 50 which carries with it, as it moves,

point of piece 50 and parts moving thereand gear-wheel 52 is so mounted as to permit it to revolve on shaft 53in one or both directions when shaft 53 is at rest or in motion and pressure is applied to a suitable point of wheel 52 for the purpose. In the construcof wheel- 52 is secured by mounting it upon 'the bearing is sufficient to enable shaft 53 to part motion to piece 50 and parts connected therewith but not sufficient to. prevent the pressure is applied in either direction by means of handle P which, operated by hand, communicates lateral motion to carriage N and piece 50 when and as desired.

From the foregoing description, the mode of operation of the phonograph, forming the sub ect-matter of this invention, in recording and reproducing sound, will be readily understood. After winding up the main spring in the manner described, a record-tablet, provided with a surface of material suitable for making therein a record of sound, or a record-tablet having a sound record alread made thereon, is placed upon plate C, shalt K passing through a hole at the center of the record-tablet. B means of handle P, shaft K is moved latera ly to right or left with car described, until a desired, proper osition of record-tablet B is obtained, whic lowered, rest near the circumference of record-tablet B. v If the record-tablet carries, a record made thereon, stylus s will adjust itself to the record-groove. Screw 37 andmetahpiece 38 being properly adjusted as describe Wheel 30 is relieved from the pressureof the piece of leather 32 carried by lever-arm 33 and the phonograph'is set in motion by the action of the main spring; Record-tablet B thereupon revolves with the revolution of shaft K m'the manner described and is simultaneously moved across and fed to the point of stylus s by reason of the latel'fll' motion communicated to revolving shaft Kjthrough worm 8, shaft 53, wheel 52, carriage N and niece 50 with which carriage N is provided. if the fecdrd-tablet B employed was provided with a surface of suitable, record ng material when, the phonograph was set motion and if, sound-waves pass order to secure the return to the starting with, carriage N is provided with a handle P tion shown in the drawings such revolution riage N and connected parts in the manner shaft 53 in such manner that the friction at cause wheel 52 to revolve With it and to im-- revolution of wheel 52 upon shaft 53 when position may be one where stylus's will, upon being ered, will adjust itse through the horn I and impinge upon the diaphragm of sound-box J, stylus s will vibrate aterally'or vertically, according to the form of sound-box employed, as is well understood, and will form in the recording material, a spiral groove of lateral or vertical undulations, constituting a sound-record. The spiral-groove constituting the sound-record may begin near the circumference and end near the center of the record-tablet B or may begin near the center and end near the circumference thereof or be otherwise formed as desired. If, on theother hand, the recordtablet B employed had a sound-record already made thereon when the phonograph was set in motion, st lus 8, upon being lowf to the record-groove and the lateral or vertical undulations of the record-groove will cause the stylus to vibrate and communicate its vibrations to the diaphragm of sound-box J and thus reproduce the sounds originally recorded.

As above stated, shaft K, in addition to revolving, moves laterally in the arc of a circle while the phonograph is in operation. The lateral motion in the arc of a circle to be communicated to revolving shaft K is determinedby the lateral movement necessary to feed the revolving record-tablet B, provided with a 'surface'of suitable, recording-material or having a sound-record made thereon, to thepoint of the stylus. In other words, at all times during one revolution of the recording-tablet B, shaft K is moved laterally in the are of a circle a distance suflicient to feed the revolving, spiral record-groove of a sound-record continuously to the point of I movement of shaft ,upon wheel 55 and upon the relation existing the stylus. This ailgustment of the lateral and of the spiral line of the record-groove is secured in a phonogra h made according to this invention by t e proper adjustment of the above mentioned parts, which communicate the lateral motion referred-to from the main spring, and depends mainly, as will be well understood,

between-the circumferential rack, with which piece 50 is provided, and wheel 52. The extent of the required later-a1 movement of shaft K, during one revolution of record-tablet B, being determined with. reference to the distance between adjacent arts or threads of a spiral record-groove, w lether in reproducing sound from a given record or in recording sound by making a spiral recordgroove, or, in other words,- being determined by the pitch of the spiral line of the record-' groove, the proper adjustment for the purpose of the necessary parts is readily made, as is well understood. Obviously, any adjustment employed in recording records of sound will be suitable for re reducing sound from a record made with tiat adjustmentq but the adjustment should, preferably" The advantages of a phonograph made in accordance with this invention will be clear to those skilled in the art to which it appertains. By it there is obtained a practical sound-recording and sound-reproducing a' paratus, which can be constructed at small cost and without difiiculty.- Moreover, in the reproduction of sound, by means of a phonograph embodying this invention, from sound-records, the record-groove passes across and is fed to the point of the stylus and the wear of the record caused in phonogra hs wherein the record-groove ropels the sty us across the face of the recor by means of the pressure exerted upon the stylus by the Walls of the record-groove is obviated.
